It is always difficult to tell when Facebook is testing new features / formats because they roll out so many variations to differrent user segments. So with that caveat, below appears to be a new format for tagged users. When you tag a user on Facebook, the name now appears highlighted fully in a Facebook-blue shade. The result is a clearer indication that the name is an 'entity'- it is hyperlinked, non-editable, etc. More interestingly, it occurs at a time when Facebook has rolled out Places - where user tagging is a key feature (and a differentiated one too). It is my hope that this is the beginning of a more robust tagging experience.
